Carmex Carbide Mini Thread Mills are compact, high-performance tools designed to thread-mill UN family threads with precision, speed, and reliability. Built for production environments and precision work, they handle a wide range of materials while supporting deep-hole applications.

• Thread compatibility: UN family threads (UNC, UNF, UNEF, UNS) supported for versatile threading in a single tool configuration.
• Size and shank: No. 2 and No. 3 cutting diameters, 56 mm overall length, MT7 shank for broad machine compatibility.
• Material and coating: Sub-Micron MT7 carbide with a multi-layer Titanium Aluminium Nitride (TiAlN) coating (ISO K10–K20) for superior wear resistance and extended tool life.
• Through-coolant efficiency: Coolant through the flutes enhances lubrication and chip evacuation, especially effective in deep-hole threading.
• Flute design: Spiral flutes provide a smooth cutting action, while a 3–5 flute configuration reduces machining time and improves stability.
• Performance at speed: Optimized for medium to high cutting speeds, enabling faster cycle times without sacrificing thread quality.
• Materials and tooling window: General-purpose performance across most materials, with proven capability to machine hardened workpieces up to 45 HRc.
• Versatility: The same tool can produce a wide range of thread pitches and can generate both internal and external threads, simplifying tooling strategies.

Whether you’re producing precision fasteners, automotive components, or embedded threaded features in engineering parts, these mini thread mills deliver dependable, accurate threads with reduced downtime. The short tool profile reduces cutting forces and deflection, helping prevent broken taps and ensuring consistent results in deep-hole milling. The combination of a high-hardness carbide, robust TiAlN coating, and through-coolant design translates to longer life, fewer tool changes, and repeatable thread quality across a variety of applications.
